Mr. Stank is that one guy in your friend group who always 'stanks'. This can be taken literally or metaphorically. The most common use is when someone stinks on both the inside and the outside. The one who regretfully succeeds as both is then named Mr. Stank.
Literally: "You stink, Mr. Stank."
Metaphorically: "Look at you, Mr. Stank, stankining our mood."

Friend 1: "What's that smell?"
Friend 2: "Oh, that's just our 'friend' Mr. Stank."
